Umehluko nokufana phakathi kwe-S275JR ne-S355JR yensimbi

Iyethula:

Emkhakheni wokukhiqiza insimbi, amamaki amabili avelele - i-S275JR ne-S355JR. Zombili zingezezinga le-EN10025-2 futhi zisetshenziswa kabanzi ezimbonini ezahlukahlukene. Nakuba amagama abo ezwakala efana, la mazinga anezakhiwo ezihlukile eziwahlukanisayo. Kule bhulogi, sizocubungula ukuhlukana kwazo okukhulu nokufana kwazo, sihlole ukwakheka kwazo kwamakhemikhali, izici zemishini, namafomu omkhiqizo.

Umehluko ekubunjweni kwamakhemikhali:

Okokuqala, ake sibhekane nomehluko ekubunjweni kwamakhemikhali. I-S275JR iyinsimbi ye-carbon, kuyilapho i-S355JR iyinsimbi ephansi ye-alloy. Lo mehluko usezicini zabo eziyisisekelo. Insimbi ye-carbon iqukethe ikakhulukazi i-iron ne-carbon, enamanani amancane ezinye izakhi. Ngakolunye uhlangothi, izinsimbi ze-low-alloy, njenge-S355JR, ziqukethe izakhi ezengeziwe ze-alloying ezifana ne-manganese, i-silicon, ne-phosphorus, ethuthukisa izakhiwo zabo.

Ukuziphatha kwemishini:

Mayelana nezakhiwo zemishini, zombili i-S275JR ne-S355JR zibonisa umehluko omkhulu. Amandla amancane okukhiqiza we-S275JR ngu-275MPa, kanti awe-S355JR angu-355MPa. Lo mehluko wamandla wenza i-S355JR ilungele izinhlelo zokusebenza zesakhiwo ezidinga amandla amakhulu ukuze zimelane nemithwalo esindayo. Kodwa-ke, kufanele kuqashelwe ukuthi amandla aqinile we-S355JR angaphansi kwalawo e-S275JR.

Ifomu lomkhiqizo:

Ngokombono wefomu lomkhiqizo, i-S275JR ifana ne-S355JR. Womabili amabanga asetshenziswa ekwenzeni imikhiqizo eyisicaba nemide njengamapuleti ensimbi namapayipi ensimbi. Le mikhiqizo yakhelwe ukusetshenziswa okuhlukahlukene ezimbonini kusukela kwezokwakha kuye kwemishini. Ngaphezu kwalokho, imikhiqizo eseqediwe eyenziwe ngensimbi yekhwalithi ephezulu egoqwe nge-hot-alloy ingaphinde icutshungulwe ibe yimikhiqizo ehlukahlukene eqediwe.

I-EN10025-2 ejwayelekile:

Ukuze sinikeze umongo obanzi, ake sixoxe ngezinga le-EN10025-2 elisebenza ku-S275JR naku-S355JR. Leli Zinga LaseYurophu licacisa izimo zobuchwepheshe zokulethwa kwemikhiqizo eyisicaba nemide, okuhlanganisa amapuleti namashubhu. Kuphinde kufake nemikhiqizo eseyiqediwe eqhubeka nokucutshungulwa. Leli zinga liqinisekisa ikhwalithi engaguquki kuwo wonke amabanga ahlukene kanye nezimfanelo zensimbi engeyona i-alloy egoqelwe ngokushisayo.

Yini i-S275JR ne-S355JR abafana ngayo:

Naphezu kokungafani kwazo, i-S275JR ne-S355JR zinezinto ezifanayo. Womabili amabanga ahambisana namazinga e-EN10025-2, abonisa ukunamathela kwawo ezinyathelweni eziqinile zokulawula ikhwalithi. Ngaphezu kwalokho, banezinhlobonhlobo zezicelo ezimbonini ezihlukahlukene ngenxa yezakhiwo zabo ezinhle, kuhlanganise nokushisela okuhle nokucutshungulwa. Ukwengeza, womabili amabanga ayizinketho ezidumile zensimbi yesakhiwo futhi anganikeza izinzuzo zawo ngokuya ngezidingo ezithile.
